Valleys are smaller than ice sheets, have longer lengths than widths, and only cover a small area. They are also known as Alpine or Mountain Glaciers. Large-scale ice sheets, commonly referred to as Continental Glaciers, encompass 10% of the territory on Earth.
More substantial than Alpine or valley glaciers are continental glaciers, also referred to as ice sheet glaciers. With the exception of the peak tops, they cover the entire continent. During the previous Ice Age, the majority of Canada and the northern portion of the United States were covered by ice sheets. Currently, Antarctica and Greenland are the only extreme polar locations with continental glaciers. Large portions of Canada, Europe, and Asia were once covered by continental glaciers, and these glaciers are to blame for many of the regions' distinctive geographical features. On land, glaciers develop. They are composed of snow that has fallen and has been compacted over many centuries into ice. Due to the influence of gravity, they progressively descend. The polar regions, including Greenland, the Canadian Arctic, and Antarctica, are home to the majority of the world's glaciers. Ice sheets, ice caps, and outlet glaciers are the three different forms of continental glaciers. An area greater than 50,000 square kilometer's is covered by an ice sheet. An ice sheet is another name for a continental glacier. The reason why these ice sheets are called glaciers is because they cover continental land masses. Presently, enormous ice sheets cover Greenland and Antarctica.
